To all whom it may concern.-

Ee it known that I, CHARLES H. HANSEN, a citizen of the United States, and a resident of Racine, in the county of-Racine and State of lVisconsin, have invented certain new and usefullmprovements in Brushes; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates especially to that class of brushes which are employed in scraping and smoothing the interior surfaces of tanks and vats used in breweries, distilleries, vinegar-factories and similar establishments; and it consists in certain peculiarities of construction and combination of parts, as will be fully set forth hereinafterandjsubsequently claimed;

In the drawings, Figure 1 is a side elevation of a brush embodying my present-invention, parts being shown in section or broken away to better illustrate certain details of construction Fig. 2 is a detail sectional View on the line 2 2 of Fig; 1. Fig. 3 is a plan view with the adjustable handle and its attachments partly broken away or in section.

Referring to the drawings, Arepresents the back of a brush, through which bunches of wires B B are passed in the usual mannerof making a wire brush, the said back being supplemented with a covering-plate O, The brush is placed back down in a frame or casing closely fitting the same and of a height equal to that of the brush. I next form a mixture by adding a pound of litharge to a quart of boiled linseed-oil and stir in a sufficient quantity of ground emery or carborundum or other granular substance until the whole mass is of the consistency of a soft paste, and pour this mass into the frame or casing until the whole brush is covered thereby, as shown at D, Fig.

1, into a solid cake, with the ends of the wires slightly projecting therethrough, if desired,

and let the mass'harden for about twentyfour hours and then remove the frame or casing. Qrdinarily I prefer to let the extreme ends of the described bunches of wire slightly project through the cake, as shown; but for some work I would grind on the brush flat, thus getting a solid brush for scraping or planing surfaces. The chief object of this treatment of the brush is to keep the tufts of (lie model.)

wires stiff and rigid, so that they will scrape the surface to which they are applied instead of being bent over, so as to merely rub the same, and I can accomplish this rigidity by using, say, plaster-of-paris for the filling agent; but I prefer sharp granular material, such as ground carborundum, (or

emery or even pulverized glass or sand from a foundry rattle-box or the like,) because this sort of filling is useful as always aiding in the described scraping action of the brush.

E E represent two loops secured, as by screws a a, to the brush-back plate G, these screws being of suitable length to unite the plate (3 to the brush-back proper, A, if desired, and said loops E E are formed with flanges or webs h l) and c c at the ends thereof. The flanges b hon one of the loops are perforated with square holes to receive the squared portions 6 next to the heads of headed bolts F F, while the flanges c c on the other loop are provided with round holes to admit the passage therethrough of the screw-threaded ends of saidbolts, which have rounded shanks, as shown, and which bolts are held in place by nuts N N. G H are sleeves fitting upon the said rounded shanks of the bolts F F between the flanges 19 c b c of the loops E E, and brazed or otherwise rigidly secured to the sleeve H is a rod I, terminating in a socket .I for the reception of a handle or pole K, held in place by means of the lugs ff on a split ring 9 on the outer end of the socket J, headed screw-bolt h, and thumb-nut t', the

said socket ,bein g split or cut out, as shown at j, to permit'the said lugs f f to be drawn toplace thereon, at the desired point to which it has been adjusted,by the set-screw it (which is preferably a thumb-screw) and having a depending fork we (only one f urcation of which is shown in Fig.-1) to receive the flattened up- 7 per end of a short rod M, pivoted thereto, as shown at n, the other end of said rod M being brazed or otherwise secured to the sleeve G.

The operation of my device will be readily understood'from the foregoing desc tion of its construction, taken in connection with the accompanying drawings. 'When it is desired to vary the angle at which the brush'is set,

. the thumb-screw 7c is loosened and the sleeve L moved on the rod I the proper distance in the required direction :until the desired inclination of the brush is accomplished, when the screw 70 is tightened again. Similarly by loosening the thumb-nut 1; the handleor pole K maybe released from the socket J and removedand one of greater orless length substituted therefor and clamped to place in the manner already described. This Will be found particularly useful in scraping the interiors lengths would be of tall vats or tanks, when from time to time as the work progresses after the upper part has been scraped handles or poles of shorter more conveniently employed, till finally when near the bottom of the vat or tank both the nuts N N (which are also preferably thumb-nuts) are removed and the bolts F F thenwithdrawn, so that the described adjustable hand'le and attachments G H I J K L M can all be removed to enable the workman to finish his task of scraping by the use of the loops EE as handles.

While I have illustrated my invention in' connection with a flat brush, it will be under- I stood that so far as the described filling and stiffening of the scraping-tufts is concerned it is equally applicable to round revolving brushes or to one havin other than wiretu fts I and that my described adjustable handle may spaces between the said tufts being'filled with hardened plastic material.

2. 'lheeombination with a brush of a pair of revoluble sleeves connected to the backing or frame of the brush, a pair of rods secured to said sleeves, a sliding sleeve on'one rod pivotally connected to the other rod, and means for holding said sliding sleeve in its adjusted position. I

3; The combination with a brush of a pair of removable bolts connected to the backing or frame of the-brush, sleeves revoluble on said bolts, a pair of rods secured to said sleeves, a slidin'g'sleeve on one rod pivotally connected to the otherrod, and means for,

holding said sliding sleeve in its adjusted position.

at. The combination with a brush of a pair of loops secured to the backing or frame of of rods'secured to said sleeves, a sliding sleeve on one rod pivotally connected to the other rod, and means for holding'said sliding sleeve in its adjusted position.

'5; The combination with a brush of a pair of rods of unequal length pivotally secured to the backing or frame of the brush, a sliding sleeve on one rod pivotally connected to the other rod, means for holding said sleeve the brush,removable bolts connecting said loops, sleeves revoluble on said bolts, a pair in its adjusted position, a pole-socket secured to the longer rod, a handle'or pole,andmeans forremovably clamping the latter in place.

within said socket.

In testimony that I claim the foregoing I have hereunto set'my hand, at Milwaukee, in

the county of Milwaukee and State of lVisconsin, in the presence of two witnesses.
